At our sawmill here in Troy, TN, we are required to send out a warning notice concerning the hazards of breathing wood dust with every shipment of lumber. Unka Jesse in Tennessee : > Hi to all, > I am told that most hard woods that we work that produce dust are bad for us, i surpose when woodworking was done at slower speeds with shavings instead as now with routers at high spindle speeds. > I surpose that metal machining that we do at work with very high spindle speeds and large feed rates(15,000 to 30,000RPM) and flooded with coolant/cutting lubricants we get a mist which we need special collectors/Vacumn cleaners so that the workshop does not end up in a haze. > I would think that with Health and Safety that this has been looked into and we are protected againist harm(I hope). > Not the kind of thing that we encounter in our home workshops except for wood, and a vacumn can take care of that. > On another subject what is everyone making at the moment in their workshops. > yours for now. > John Burridge Raining in Oxford MODEL ENGINEERING DISCUSSION LIST.
